Apart from its unique performance properties and environmental benefits the Victrex PEEK-based honeycomb provides numerous other advantages including excellent impact resistance; unlike an aluminium or thermosetting honeycomb, PlastiCell's honeycomb will not remain deformed by accidental impacts during machining or assembly of the part and, due to the material's high temperature performance, the honeycombs can operate continuously up to 220°C (428°F, a thermoformable honeycomb core allows for the production of parts with short cycle times using an autoclave-free process. There is no size constraint as it is possible to make an endless honeycomb using PlastiCell's manufacturing process. Part size limitation is dictated by the hydraulic press platen size.

除了其独特的性能特性和环境效益外，VICTREX聚醚醚酮基蜂窝芯材还有很多其它优点，比如优良的耐冲击性，不像铝或热固性蜂窝芯材，PlastiCell蜂窝芯材不会在部件加工或安装期间由于受意外撞击而变形，因为该材料具有高温性能，（此蜂窝芯材的操作温度可连续达到220℃（428℉），生产热压成型的蜂窝芯材的周期短，不使用高压反应釜加工，没有尺寸限制，用PlastiCell工艺可以生产连续蜂窝芯材，液压模板的尺寸限制部件的大小。

Unfortunately, I am not the parents in this exceptionally busy with their parents during the Spring Festival I have been subjected to numerous White-eyed, looking at the jump's cousin cousin who can not help but worry for their future whether it will have this experience.

可惜我不是父母在这个分外冷清的春节期间我已经遭受到父母无数的白眼，看到眼前活蹦乱跳的堂弟堂妹们也不禁为他们担心，将来是否也会有此遭遇。
